I was getting the below error in K2, I suspect the code "strDestinationQueue = K2.ActivityInstance.Destinations.Item(0).DestQueue.Name" was causing the issue
Type 'SourceCode.KO.DestQueue' in assembly 'KO, Version=3.6262.1.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.
I notice from a similar issue the below hotfix fixes the problem which I tried and it did, however the KO.dll version I had was 3.6262.1.0 and the hotfix version was 3.6090.0.0. Will this cause me an issue as it look like I have gone back some versions?
K2.net 2003 Hotfix 2
